naces, etc, and has reference specifically to a construction whereby the readily controlled in order that any individual arm may receive a supply of the cool ing fluid in proportion to the amount of heat to which said arm is exposed.

More specifically the invention relates to stirring means which may be employed for agitating a mass or masses of heatedmate rial, said material either being in bulk or disposed upon a plurality of separate floors or earths, the construction of the stirrer being such that a supply of cooling fluid is suppliedto' each one of a plurality of arms while the fluid which has been caused to circulate through any individual arm is returned separately to an individual outlet or overflow.

By cont-rolling the outflowing fluid from each of the several arms separately, the condition of each of said arms can be readily ascertained by the temperature of the fluid flowing therefrom, and the flow through either of said arms can be proportioned to the heating effect of an arm upon the cooling fluid passed thercthrough. In this way complete and accurate control is had of the temperature of each of the several arms.

In the drawings which illustrate an embodiment of this invention and on which the same reference characters refer to the same elements in each of the several views,Fig'- ure 1 is a vertical section through a shaft and arms of a stirring device constructed according to this invention, the stirrer being shown as located in a conventional form of receptacle, and in this specific instance the shaft being shown as composed of the sections A, i5. O. 1). Fig. 2 is a sectional elevation of the lower member A of the shaft shown in Fig. 1. Fig. 3 IS a plan view, Fig. 4 1s a transverse scction taken on the line 11; Fig. is a transverse section taken on the line 22; Fig. 6 is a transverse section taken on the line 3-3; and Fig. 7 is a transverse section taken on the,line'4-4 of the member shown by Fig. 2. Fig. 8 is a vertical section of the flow of a cooling medium through a shaft and arms may be member B of the shaft asshown by Fig. 1. Fig. 9 is a transverse section on the line 1-1 Fig. 10 is 'a transverse section on the line 2-2; Fig. 11 is a transverse section on the line 3-3; and Fig. 12 is a transverse section on the line 44 of the member shown by Fig. 8. Fig.13 is a sectional elevation of the member C of the shaft as shown by Fig. 1.

Fig. 14} is a transverse section 'o'n the linev 1 1 Fig. 15 is a transverse section on the line 22; Fig. 16 is a transverse section on the line 33 and Fig. 17 is a transverse section on the line 4-4 of the member shown by Fig. 13. Fig. 18 is an elevation of the member D of the shaft shown by Fig. 1.- Fig. 19 is a plan view of the top of said sec tion. Fig. 20 is a plan view of the bottom of said section looking upward towards said member as shown by Fig. 18. Fig. 21 is a schematic development of the three members of the shaft A, B and C shown by Figs. 1, 2, Sand 13, showing clearly the course talten by the cooling fluid through the several' channels formed in the shaft by saidmer'nbers.

Each of the sections of the members A, B and C is shown when looking downward or in the direction indicated by the arrows placed near the section lines which are shown by Figs. 2, 8 and 13.

The'reference'letter E represents a pipe by which a cooling .fluid, preferably water, is supplied to the shaft and arms. This pipe is in open communication with the passageway which extends downwardly through the center of the shaft as a whole and which is formed by the passageway to in the member D, co in the member C, to in the member B, and 10 in the member A, the'se passageways formed in the several members being adapted to form a continuous passageway as shown by Fig. '1 when the several members are assembled to form a shaft.

Each of the several members A, B, C and D are composed of an exterior wall or shell,.

an interior wall by which the passageways referred to above are formed, and a plurality of radial ribs of partitions connecting these two walls and forming passageways for the cooling fluid.

Referring to Fi 1, the lowermost member A is provided at the bottom with a step bearing T upon which the shaft is adapted to be supported. -The partitions and the central wall in this section are not continued to the turn through said arm into the passage 3,

bottom of the member; but terminate a short distance above said bottom, leaving a eflect of such interruption being to cause the up the shaft;

fluid ascending through the several passages A to-bediverted through the pipes 1) into the ends of the arms (1 instead of passing directly or example, looking at Fi 1 it-will'be seen that water being admit ed through the pipe E will pass down through thepassages w,*"w, 7,0 'w' into the space it,

Q from thence it will pass up through the left hand passage 3 until stopped by the partition (i which will cause it to pass, out through the pipe pinto the end of the arm d and then re-- and will be discharged through the overflow pipe shown at the top and left hand side of said figure. a Water from the ipe E will also take the course just indicate but will pass from the space If up through the passage 6 until arrested by the partition (1, when it will pass through the pipe p into the arm d,

thence up through the passage 6. In general it may be stated that a similar course is provided for the water through each one of the several arms, the purpose being to cause the water to be discharged into each of the several arms and to compel the water lowing from each of the several arms to be confined in a separate passage. The specific 0011- struction ado ted to accomplish this result the fluid ascends the shaft, is divided into two passages, each of which provides a return channel from one of the arms. For example, starting from space tin the bottom of the member A,the water passes upward through the passage 1 until it meets the par tition (1, then passes out through pipe 7) back through. the arm above the partition (1, thence upwardly as heated water through the passageway 1*. By reference to each of the succeeding figures of the drawing it will be; noticed that this passageway 1. is mainway up to its individual overflow or waste pipe. In like manner thewater which passed up through the passageway 1 and which was not intercepted by the partitiond (see Fig. 5), continued upward through the other half, of the now subdivided passageway 1, namely, the passageway 1*, until it is intercepted by the partition d (see Fig. 7 {which deflects itthrough the pipe and arm whence it returns and 3 passes up and out through the passage 1. Itisnot deemed necessary to trace the passage of the water from each of the passageways 2, 3', 4, 5 and 6, as the same general scheme of nota tion is adopted inlettering thedrawings. By reference to Fig. 21 it will be seen that the passage 1 is split at thefirstfipartition into the two passages 1 and 1 above thesecond partition the passage corresponding to 1 becomes 1". Each of the other assages, namely, 2, 3, 4, 5 and 6, are subdivided in the same manner, the only exception with regard to the continuity of each of the several assages occurs in the upper part of the mem er B and the lower part of'the member C, where, as a matter of convenience and to save weight, the partitions which would otherwise exist between some of the ascending cold water passages are dis ensed with and large passages marked H, I, ,-K, result from such change of structure.

All of the partitions, except those which confine the heated water flowing from the several arms, could be dispensed with without departing from this invention, the speciiic structural arrangement shown by the drawings being adopted to secure strength.

Each of the overflows or outlets is controlled by a valve 8 by means of which the amount of water flowing through each arm can be regulated.

It will be understood that in practice mechanism is provided for rotating this shaft, but as such mechanism forms no part of the present invention it has not been shown or described.
